ISSAC, the International Symposium on Symbolic and Algebraic Computation, is an academic conference in the field of computer algebra. ISSAC has been organized annually since 1988,^[1] typically in July. The conference is regularly sponsored by the Association for Computing Machinery special interest group SIGSAM, and the proceedings since 1989 have been published by ACM.^[2] ISSAC is considered as being one of the most influential conferences for the publication of scientific computing research.^[3]

The first ISSAC took place in Rome on 4–8 July 1988. It succeeded a series of meetings held between 1966 and 1987 under the names SYMSAM, SYMSAC, EUROCAL, EUROSAM and EUROCAM.^[4]

• The Richard D. Jenks Memorial Prize for excellence in software engineering applied to computer algebra is awarded at ISSAC every other year since 2004.
• The ISSAC Distinguished Paper Award is awarded at ISSAC since 2002 to authors that display excellence in areas that include, but are not limited to, algebraic computation, symbolic-numeric computation, and system design and implementation.^[5]
• The ISSAC Distinguished Student Author Award is awarded at ISSAC since 2004 to authors if they were a student at the time their paper was submitted.

Typical topics include:^[6]

• exact linear algebra;
• polynomial system solving;
• symbolic summation;
• symbolic integration and computational differential algebra;
• computational group theory;
• symbolic-numeric algorithms;
• the design and implementation of computer algebra systems;
• applications of computer algebra.
